Respectfully snipped -
When I first watched her interview, I was certain it was another spontaneous Dina moment. After further thought, I'm not so sure. I agree Dina was likely on a business trip related to the WDS. Danya Bacchus, NBC interviewer, has been covering this case since the beginning. I tend to believe Dina contacted Danya. I'm not sure Dina didn't have help from her attorneys or PR firm. IIRC, this is the first interview where Dina is not in a closeup talking. It appears to me this was intentional. Then the side step of NOT mentioning Adam is actually a good move on their part. Throw suspicion on Adam, away from Dina and Nina by using the comment about them not being there. Anyone who really knows this case, knows Nina admitted to being on the property. BUT, to the average reader this may come across as Dina saying she and her sister have alibis. Dina chose her words wisely. Dina didn't say they were not on the property that night (I know for a fact I was not there and neither was my sister). Where is there? Imo, not there during the murder.
Another interesting part of the interview, Dina does not mention XZ. Instead she said Rebecca was the only person there at the time. No way do I believe Dina has changed her mind about Rebecca and XZ both being there. In my opinion, there may be a restraining order protecting XZ or Dina was protecting her image by not verbally attacking a minor. This shows control. I tend to believe it was rehearsed. PR at work.
You asked about the timing of the interview. Scottsdale Soccer has a Blackhawks Max Shacknai Invitational. The tournament was Feb. 20th-22nd. I may be way off here, but I think the Feb. 7th interview had a targeted audience. The interview went viral, even reaching prime media outlets. If you think about the group of people participating in this event, I'm sure there would be plenty of talk amongst each other regarding Dina and Rebecca's death. First topic of discussion, did you see Dina's recent interview? Followed by, Dina said she nor her sister were there. Did you notice she doesn't mention Adam? I think you get my point.
